Coarse, Partial-Thread Fastener — A4‑70 Stainless Steel Key benefits - High corrosion resistance: A4 (marine-grade) stainless steel resists rust and pitting in wet, salt, and chemically aggressive environments. - Strong performance: Property class 70 (A4‑70) provides high tensile strength for reliable mechanical fastening under load. - Practical thread design: Coarse thread speeds assembly and improves holding in softer materials; partial threading leaves a smooth shank for better shear strength and accurate alignment. What this product does - Provides a durable fastening solution where both tensile and shear loads are present. - Combines the grip advantages of a coarse thread with the structural benefits of a partially threaded shank. - Suited for repeated assembly/disassembly thanks to robust material and thread form. Compatibility and function - Works with matching coarse-thread nuts or tapped holes of the same thread standard and size. - Partial thread design lets the unthreaded shank act as a load-bearing surface, reducing stress concentrations in shear applications. - Appropriate for use wherever A4‑70 stainless fasteners are specified for corrosion resistance and strength. Material and performance highlights - Material: A4 stainless steel (marine‑grade), property class 70. - Corrosion resistance: Effective in saltwater, outdoor, and many chemical environments. - Mechanical behavior: Designed to deliver dependable tensile strength and improved shear capacity when used as intended. Typical use scenarios - Mounting handrails, stanchions, or fittings on boats and marine platforms where salt exposure is a concern. - Assembling outdoor stainless steel structures, canopies, or architectural fixtures exposed to weather. - Fixing equipment frames, brackets, or components in food processing or chemical facilities that require corrosion-resistant fasteners. Notes for selection - Ensure matching thread size and coarse-thread specification for compatibility. - Choose partial-thread length appropriate for the combined shear/tensile requirements of your application.
